The acceleration to 100 km/h is faster with 0.2 seconds – 4.5 s and the top speed is 319 km/h (198 mph), which is 12 km/h (7 mph) more.

The overall weight of the car is 1920 kg, which is a lot, but the performance is brutal. The fuel consumption is 10.5 litres per 100 km (26.9 mpg imp) with 244 g/km of CO2 – combined cycle.
